Classification of Engineering drawings as per Standards

AI Thread Summary
Level 1 engineering drawings refer to conceptual and developmental designs, while Level 2 pertains to production prototypes and limited production, and Level 3 involves finalized production drawings. The ASME Y14 series does not classify drawings using these levels; instead, this classification is mentioned in military standards. The discussion highlights a potential confusion between educational courses on ASME Y14 and actual drawing classifications. It emphasizes the importance of clarity in Level 3 drawings, ensuring all details are precise and unambiguous. Understanding these classifications is crucial for effective engineering communication and documentation.

Hello,

What is Level 1 engineering drawing? What does it mean?

Is there any particular section dealing about classification of engineering drawings in ASME Y 14 series.

Please throw some light on this

Thanks

Anyone, please share their knowledge
 
I can't say I ever remember anything called "Level 1" type of drawing in any of the ASME Y14 series. I'll have to take another look through to make sure.

Perhaps it is in reference to an assembly level of a drawing. In other words, the most basic level is a part drawing. The next higher level could be a subassembly level, the next higher level another subassembly. The highest level being the top level assembly drawing.
 
Thanks Tyroman and FredGarvin.

As FredGarvin pointed out, it is not part of ASMEY14, but was mentioned in MIL standard.
 
In a nutshell: Level 1 – Conceptual and Developmental Design, Level 2 – Production Prototype and Limited Production, Level 3 - Production.
In level 3 drawings, all of your i's must be dotted and t's crossed, with nothing left open to varying interpretations.
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
